Bitnami Secure Image for JanusGraph

What is JanusGraph?

JanusGraph is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster.

Overview of JanusGraph Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

docker run --name janusgraph bitnami/janusgraph:latest

⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new Bitnami Secure Images initiative. As part of this transition:

  • Granting community users access for the first time to security-optimized versions of popular container images.
  • Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
  • Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
  • For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the Bitnami Secure Images announcement.

Why use Bitnami Secure Images?

  • Bitnami Secure Images and Helm charts are built to make open source more secure and enterprise ready.
  • Triage security vulnerabilities faster, with transparency into CVE risks using industry standard Vulnerability Exploitability Exchange (VEX), KEV, and EPSS scores.
  • Our hardened images use a minimal OS (Photon Linux), which reduces the attack surface while maintaining extensibility through the use of an industry standard package format.
  • Stay more secure and compliant with continuously built images updated within hours of upstream patches.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • Hardened images come with attestation signatures (Notation), SBOMs, virus scan reports and other metadata produced in an SLSA-3 compliant software factory.

Only a subset of BSI applications are available for free. Looking to access the entire catalog of applications as well as enterprise support? Try the commercial edition of Bitnami Secure Images today.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Get this image

The recommended way to get the Bitnami JanusGraph Docker Image is to pull the prebuilt image from the Docker Hub Registry.

docker pull bitnami/janusgraph:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

docker pull bitnami/janusgraph:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Configuration

Environment variables

Customizable environment variables

Name Description Default Value
JANUSGRAPH_MOUNTED_CONF_DIR Directory for including custom configuration files (that override the default generated ones) ${JANUSGRAPH_VOLUME_DIR}/conf
JANUSGRAPH_GREMLIN_CONF_FILE Path to JanusGraph Gremlin server configuration file ${JANUSGRAPH_CONF_DIR}/gremlin-server.yaml
JANUSGRAPH_PROPERTIES Path to JanusGraph properties file ${JANUSGRAPH_CONF_DIR}/janusgraph.properties
JANUSGRAPH_HOST The name of the host to bind the JanusGraph server to. 0.0.0.0
JANUSGRAPH_PORT_NUMBER The port to bind the JanusGraph server to. 8182
JANUSGRAPH_STORAGE_PASSWORD Password for the Janusgraph storage nil
GREMLIN_REMOTE_HOSTS Comma-separated list of Gremlin remote hosts localhost
GREMLIN_REMOTE_PORT Comma-separated list of Gremlin remote port $JANUSGRAPH_PORT_NUMBER
GREMLIN_AUTOCONFIGURE_POOL If set to true, the gremlinPool will be determined by Runtime.availableProcessors(). false
GREMLIN_THREAD_POOL_WORKER The number of threads available to Gremlin Server for processing non-blocking reads and writes. 1
GREMLIN_POOL The number of threads available to execute actual scripts in a ScriptEngine. 8
JANUSGRAPH_JMX_METRICS_ENABLED Turns on JMX reporting of metrics. false
JAVA_OPTIONS JanusGraph java options. ${JAVA_OPTIONS:-} -XX:+UseContainerSupport

Read-only environment variables

Name Description Value
JANUSGRAPH_BASE_DIR Base path for JanusGraph files. ${BITNAMI_ROOT_DIR}/janusgraph
JANUSGRAPH_VOLUME_DIR JanusGraph directory for persisted files. ${BITNAMI_VOLUME_DIR}/janusgraph
JANUSGRAPH_DATA_DIR JanusGraph data directory. ${JANUSGRAPH_VOLUME_DIR}/data
JANUSGRAPH_BIN_DIR JanusGraph bin directory. ${JANUSGRAPH_BASE_DIR}/bin
JANUSGRAPH_CONF_DIR JanusGraph configuration directory. ${JANUSGRAPH_BASE_DIR}/conf
JANUSGRAPH_DEFAULT_CONF_DIR JanusGraph default configuration directory. ${JANUSGRAPH_BASE_DIR}/conf.default
JANUSGRAPH_LOGS_DIR JanusGraph logs directory. ${JANUSGRAPH_BASE_DIR}/logs
JANUSGRAPH_DAEMON_USER Users that will execute the JanusGraph Server process. janusgraph
JANUSGRAPH_DAEMON_GROUP Group that will execute the JanusGraph Server process. janusgraph

Additionally, any environment variable beginning with JANUSGRAPH_CFG_ will be mapped to its corresponding JanusGraph key. For example, use JANUSGRAPH_CFG_STORAGE_BACKEND in order to set storage.backed or JANUSGRAPH_CFG_CACHE_DB__CACHE in order to configure cache.db-cache.

Using mounted configuration

The image looks for configuration files (janusgraph.properties, gremlin-server.yaml) in the /bitnami/janusgraph/conf/, this can be changed by setting the JANUSGRAPH_MOUNTED_CONF_DIR environment variable.

docker run --name janusgraph -v /path/to/janusgraph.properties:/bitnami/janusgraph/conf/janusgraph.properties -v /path/to/gremlin-server.yaml:/bitnami/janusgraph/conf/gremlin-server.yaml  bitnami/janusgraph:latest

FIPS configuration in Bitnami Secure Images

The Bitnami JanusGraph Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

  • OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.
